Alstroemeria named Stalibla

ABSTRACT

A new and distinctive Alstromeria cultivar particularly distinguished by the almost white outer petals of a very large flower especially characterized by its long elliptically shaped inner petals which terminate in a distinctive aristate tip and have a lemon yellow coloration for about two-thirds of its length from the base end, the outer portion being of the almost white color of the outer petals. The relatively narrow inside petals are also distinguished by short dark brown pencil stripes which extend longitudinally from the petal base to its tip. This plant being further characterized by its profuse year around blooming habit on an upright fast growing bush of which the cane length is about 180 cm.

BACKGROUND OF THE NEW PLANT

This Alstroemeria cultivar originated as a sport of the variety Stalbel, U.S. Plant Pat. No. 6,193 grown at Aalsmeer, The Netherlands, discovered by me at Aalsmeer in 1984 and selected for propagation and test in the course of my objective of developing new colors in the `Stalbel` family. Propagation of this sport was done under my direction by cuttings of roots with such success that propagation by dividing rhizomes was carried on through several successive generations which demonstrated clearly that the novel characteristics of the discovered sport would be retained from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWING

The accompanying color photographic drawing shows typical inflorescence, bud, and foliage characteristics of `Stalibla`, with colors being as nearly true as possible to obtain by conventional photographic procedures.
